it is colorless and tranparent liquid of ester scent and soluble in water a little bit but fairly well in organic solvent. it gets polymerized easily by light, heat, radiation and peroxides, and then becaome methacrylic resin. 

Our MMA manufacuring process is the eco-freindly process that produces MMA/MAA/HEMA/HISS by the isobutylene direct oxidation from C4 middle distiillate and the esterification reaction. We reduced waste in large degree comparing with existing ACH process with acetone and hydrocyanic acid.
